Hi all!
My company is in the process of creating a platform for the exchange of crypto currencies, gaming currencies and  currencies of the "real world".
If you want to participate in the creation of a new strong exchange, which will work just as you wish, write your suggestions here.
What we are implementing now: 
- Exchange depositary receipts (EDR) - You deposit money into an account and trading on the exchange without waiting for signature for each transaction.
 - Trade API (REST based, ) - You can trade with your own software
 - Shopping API (REST based) - You can sell and buy directly with our EDR's or cryptocurrencies through our API.
 - Interfaces for shopping carts - After starting the exchange, we plan to release a free adapters for all popular shopping carts
 - Priority robot trading - You can trade with an integrated trading robot with extra charge. The robot will support "stop loss" and "talke profit" instruments.
 - Extended security - With 2-step authorization, one-time password cards,  security tokens and smart cards (later)
 - Trade with any currency - If you can explain, how we can accept and give back the currency, we will use it
 - DDOS protection - We are using Erlang - very strong and fast server-side language. In conjunction with the DDOS-resistant hosting this will ensure the stability of the exchange.
 - Futures and options - For advanced and convenient stock trading
 
We welcome any cooperation that you can offer.
